This refers to a lack of emotion in facial expressions and body language, which can make it difficult for others to interpret the person's feelings or intentions. Loud and meaningless talking, inappropriate laughter, and uncontrollable rage are examples of positive symptoms, which involve the presence of abnormal experiences or behaviors.

Social withdrawal is a negative symptom of schizophrenia, meaning it involves a decrease or absence of normal behavior or emotions. Hallucinations and delusions are positive symptoms, involving the presence of abnormal behaviors. Inappropriate rage is not a specific symptom of schizophrenia.

Question 3

Oxygen deprivation at the time of birth is a known risk factor for

Accepted Answer

Oxygen deprivation at birth is a known risk factor for the development of schizophrenia. This may be due to the fact that the brain is especially susceptible to damage during the birth process, and a lack of oxygen can cause significant damage to brain cells that may contribute to the development of this disorder.

Question 4

Hallucinations and delusions are positive symptoms of schizophrenia, meaning that they are additional presence of something that is not typically present, rather than a loss or lack of something (negative symptom). Word salad, or disorganized speech, is a symptom commonly seen in individuals with schizophrenia who are experiencing positive symptoms. Catatonia is a separate symptom cluster in schizophrenia that involves a lack of movement, responsiveness, or engagement with the environment. Bipolar disorder is a separate disorder characterized by mood swings between depression and mania, and is not directly related to the symptoms described in the question.

Question 8

Which type of schizophrenia develops slowly and is less responsive to treatment?

Accepted Answer

Chronic schizophrenia develops slowly over a period of time and is less responsive to treatment when compared to other types of schizophrenia. Reactive schizophrenia, on the other hand, is a sudden onset of symptoms in response to a severe stressor and often has a better prognosis. Acute schizophrenia refers to the onset of symptoms over a short period of time, but it can be responsive to treatment. Paranoia is a symptom commonly found in individuals with schizophrenia and can occur in any subtype.

Accepted Answer

Catatonia is a group of symptoms that involve a disturbance in motor behavior and can be seen in several psychiatric disorders. The key feature of catatonia is a disturbance in movement, which can include periods of immobility followed by agitation. This may involve the individual holding a fixed and rigid posture, or they may repeat certain movements over and over again. It is often associated with bipolar disorder, schizophrenia, or other psychiatric conditions.

Question 12

Many researchers believe that several of the symptoms of schizophrenia result from an overabundance of receptors for the neurotransmitter

Accepted Answer

Several studies have indicated that schizophrenia may be related to the overabundance of dopamine receptors in some areas of the brain. This theory is supported by the fact that antipsychotic drugs that block dopamine receptors are effective in treating symptoms of schizophrenia, such as hallucinations and delusions.

Question 13

Oxygen deprivation at the time of birth is a known risk factor for

Accepted Answer

Oxygen deprivation at birth has been linked to a higher risk of developing schizophrenia later in life. There is little evidence linking it to the other disorders listed.

Question 14

Mrs.Higgins believes that aliens from another planet have removed her stomach and are watching her to see how long it takes her to grow another one.Mrs.Higgins is most likely suffering from

Mrs. Higgins' belief about aliens removing her stomach is a classic symptom of delusions, which is a key feature of schizophrenia. Agoraphobia is characterized by a fear of leaving one's home or being in places where escape or help may be difficult in the event of a panic attack or other problem. Bipolar disorder is a mood disorder characterized by alternating episodes of depression and mania. Dissociative identity disorder involves the presence of two or more distinct personality states. None of these conditions fit Mrs. Higgins' symptoms as well as schizophrenia does.

Question 16

The relationship between the season of the year in which people are born and their subsequent risk of schizophrenia best highlights the role of ________ in this disorder.

Accepted Answer

The relationship between the season of the year and the subsequent risk of schizophrenia suggests that viral infections during prenatal development may play a role in the development of the disorder. This is supported by research showing increased risk of schizophrenia in individuals born during the winter and early spring months when viral infections are more common.

Question 17

A disorder in which a person loses contact with reality and experiences irrational ideas and disordered perceptions is

Accepted Answer

The description given in the question matches the symptoms of a psychotic disorder.

Mr. James is experiencing false beliefs or perceptions that are not grounded in reality, known as delusions.

Question 20

Therapeutic drugs that block dopamine receptors are most likely to reduce

Accepted Answer

Dopamine is involved in the regulation of perception and emotion, particularly in the mesolimbic pathway, which is associated with the experience of reward and pleasure. Excess dopamine activity in this pathway has been linked to the development of psychotic symptoms such as hallucinations and delusions. Therefore, drugs that block dopamine receptors, such as antipsychotics, are commonly used to treat these symptoms in conditions like schizophrenia and bipolar disorder.
